This game needs Savage solo content and Savage 4 player.

Clemency would absolutely need to be adjusted if Savage solo content were to be introduced.

As it is now you'd be massively gimping yourself if you were to run said hypothetical content as any class other than PLD due to their utterly unmatched potential self-sustain.

Alternatively SE could develop savage content tailored to each JOB ala The Masked Carnivale, but that would require a tremendous amount of resources to develop for content that the majority of the playerbase would likely not even run once.

If tweaking the skill were up to me I'd just make it so that you can longer target yourself with Clemency.
Unless you're soloing you should pretty much never cast Clemency on yourself anyway.
